Compiling ScummVM/MinGW

Compiling ScummVM with Minimalist GNU for Windows (MinGW)

MinGW is "a collection of freely available and freely distributable Windows specific header files and import libraries combined with GNU toolsets that allow one to produce native Windows programs that do not rely on any 3rd-party C runtime DLLs".

More information can be found at the MinGW homepage

Things needed

MinGW and MSYS

• Download and install the latest MinGW Installation Manager (mingw-get-setup.exe)
• From the list of packages shown, check mingw-developer-toolkit-bin, mingw32-base-bin and mingw32-gcc-g++-bin, as well as mingw32-libz-dev from the "MinGW Libraries" section (right-click > Mark for Installation)
• Click the Installation > Apply Changes menu to install MinGW and MSYS
• Once installation is complete, you can run MSYS from inside the MinGW directory (by default C:\MinGW\msys\1.0\msys.bat)

Libraries needed

Precompiled libraries

To ease the whole process, a package of all the needed precompiled libraries has been created. All you need to do is:

• Download the precompiled libraries and the latest SDL runtime library - latest version is 1.2.15 at the time this was written, you can find the latest version here. Precompiled libraries:
  • Precompiled libraries
• Extract them to your MinGW directory (e.g. C:\MinGW)

Additional information about MinGW and Windows Vista

In order to get MinGW properly working under Windows Vista, you need to do the following: Go to Control Panel->System, and click on "Advanced System Settings" to the left. Then click on "Environment variables" and on the bottom window ("System variables"), select the "Path" variable and edit it. This variable tells windows where to look for binaries when it can't find them in the current folder. You'll find a lot of directories there separated by semicolons.

Make sure that the MinGW bin directory is included in the path (e.g. C:\MinGW\bin), which should already be included there from the MinGW installer. Also, make sure that the libexec path is included too (e.g. C:\MinGW\libexec\gcc\mingw32\3.4.2), which is needed in Vista to get MinGW properly working

MSYS primer

From the developer's webpage: "MSYS or Minimal SYStem is a POSIX and Bourne shell environment use with MinGW. It provides a hand picked set of tools to allow a typical configuration script with Bourne syntax to execute. This allows most of the GNU packages to create a Makefile just from executing the typical configure script which can then be used to build the package using the native MinGW version of GCC".

For more information, check the MinGW FAQ page

MSYS commands can be confusing for people using Windows, as MSYS emulates a Bourne shell environment, which is found in most Unix/Linux distributions. The available commands can be viewed by typing "help" in the command prompt. Help on a specific command is available by typing "help" followed by the command, e.g. "help alias".

Note that MSYS uses forward slashes between folder names, not backward slashes, as is the case with Windows. Additionally, some special characters like the space need to be escaped with a backward slash("\"). Drives are mounted to folders, so drive "C:" would be under folder "/c". Therefore, to switch to directory:

C:\Program Files\Test Folder

we would switch to:

/c/Program\ Files/Test\ Folder

The basic commands you'll need are:

cd - changes the current drive and directory
pwd - shows the current drive and directory
ls - lists files in a folder
make - makefile, used to compile projects
strip - remove debug information from executable files

Note that if you wish to run a file from the current folder, you need to specify it before the file name, i.e. if you wish to run "test" from the current folder, you should type:

./test

Building the libraries

Now, we need to compile the required libraries and tools.

NASM

Unzip the nasm archive in a folder, and copy both files to MinGW's bin directory.

pkg-config-lite

Unzip the pkg-config-lite archive in a folder, and copy the "bin" and "share" to MinGW's root directory.

SDL

Unzip the SDL archive in a folder, open MSYS, go to the SDL folder and issue these commands to compile and install the library:

./configure --disable-shared --prefix=/mingw
make
make install

It may be necessary to modify the bin/sdl-config and lib/pkgconfig/sdl.pc files (located under the mingw directory) which are just text. These files provide the compiler option information to ScummmVM and SDL is passing the -mwindows compiler option by default which will result in a valid executable, but with broken console / command-line output. These should be removed or replaced by -mconsole (though this will affect all SDL compiled binaries made by the MinGW toolchain). ScummVM's configure script should deal automatically with this issue in future as the upstream SDL project has indicated that removing this "forced" option is a WONTFIX issue.

Note the README here, especially the need to include the DirectX development headers from here to ensure that the "dsound" rather than the "waveout" / "winmm" fallback audio driver is used.

libogg

libogg should be compiled before libvorbis, libtheora and libFLAC.

sed -i '/-fforce-mem/d' configure

Then issue these commands to compile and install the library:

./configure --disable-shared --prefix=/mingw
make
make install

Compiling ScummVM

To compile ScummVM, issue the following commands inside the scummvm folder (where Makefile resides):

./configure
make

After compilation, you'll end up with a very big scummvm.exe (around 16MB). This is because debug symbols and information are embedded by default in the exe file, making it very big. To remove all the unneeded debug information from the executable, thus reducing its size by about 12MB, go to the folder where the compiled scummvm.exe file is and run the following command:

strip scummvm.exe

Compiling with Console/Text Output

By default ScummVM is compiled as a Windows subsystem application with no console output. If you need the console, you will need to apply the following patch:

diff --git a/configure b/configure

OK this should be all of it (thankfully), so you should be good to go.
